A LOCOMOTIVE TRUCK AND METHOD FOR DISTRIBUTING WEIGHT ASYMMETRICALLY TO AXLES OF THE TRUCK

摘要

A locomotive truck (26a) and method for distributing weight asymmetrically to axles (38) of the truck includes a first axle (38e) of a locomotive truck uncoupled from a traction system of the locomotive (10) and a first suspension assembly (4Oe) coupling the first axle to the truck for applying to the first axle a first portion of a locomotive weight. The truck also includes a second axle (38a) coupled to the traction system and a second suspension assembly (40a) coupling the second axle to the truck for applying to the second axle a second portion of the locomotive weight greater than the first portion so that weight is asymmetrically distributed to the first axle and the second axle so that more tractive effort may be generated by the second axle compared to a configuration wherein the weight is symmetrically distributed to both axles.
